Big stretch but I'm just seeing if anyone that has done repair work on a Sega Game Gear might know whats going on with the display. Its been a long ass time I've owned a Game Gear so what I'm seeing could be normal. Was hoping it might be some easy fix like dead capacitors but I'm starting to think it this handheld might have several issues were its not even worth trying to fix. I only have experience repairing Gameboy Colors which are less complex.

I recently purchased a Sega Game Gear from eBay that was sold as potentially not working as a repair project. Seller mentioned that he didnt have a game to test it out so it was being sold as potentially not working. Trying to figure out how much money its going to take to repair it since this repair work might not be so easy as replacing dead capacitors. I just dont want to dump a bunch of money on repairing the handheld.

I'm currently waiting on a flashcart purchased from Aliexpress to test it with a game. But I can already tell theres something weird going on with the display. Each time I turn it on it has 2 or more black horizontal lines and the light seems to dim out slowly. The brightness doesn't seem to be always consistent.
